It is very complicate to install sysinfo package on our customer box. I cannot do it for quick.

We have all diagnostic dump that is a gather of all system information., like BMC logs, RAID logs and so on.

Which info you want?

Do you think the issue is caused by faulty/loose cable or faulty RAID card?

Thanks, Guofeng

The issue is fixed.

I get the support from your RAID developer.

He confirm the issue is caused by SAS expander and is fixed in the latest SAS expander firmware update.

Thanks for your support.
